Pharyngoesophageal junction: C5-6 level
•
Videofluoroscopic recording: Frontal, lateral, and oblique
Rapid sequence filmong required for demonstration
TOP DIFFERENTIAL DIAGNOSES
•
Cervical osteophytes (indentation)
Large anterior cervical osteophytes can impinge on pharyngoesophageal junction, simulating cricopharyngeal achalasia
•
Esophageal tumor
Tumor at pharyngoesophageal junction may constrict lumen concentrically or eccentrically
PATHOLOGY
•
Usually just “poor timing” of cricopharyngeal contraction
Due to “presbyesophagus” or other cause of dysmotility in most cases
•
May occur as an isolated abnormality
